To a whom it may concern:

Be it known that I, FREDRIK BJ'URsTRoM, a citizen of the United States of America, and

" a resident of the borough of Manhattan, New

'Fig. 5 is a plan of the York city, and State of New York, have invented certain new and useful Improvements in Stamp-Canceling and Postmarking Machines, of which the following is a specification.

My invention relates to stamp-canceling and postmarking a paratus in which the letters are placed in atches edgewise on a descending chute arranged'laterally toa line of feeding, stamping, marking, and delivering rolls, from which they pass on to another lateral descending chute for removal after the stamping and canceling; and theinvention consists of certain combinations, constructions, and arran ements of 'ap aratus, as hereinafter descriied, reference being made to the accompanying drawings, in which Figure 1 is a plan v1ew of my improved,

machine. Fig. 2 is a detail in side elevation as seen looking from the bottom of the sheet containing said Fi 1. Fig. 3 is an endelevation as seen at t e leftrhand side of Fig. 1,

with the supporting-base in section. Fig. 4' is a longitudinal vertical section .on line 4 4 of Fig. 1 as viewed in the directiondndicated b the arrow at the upper right-hand. corner 0 Fig. 1. Fig. 4 is a part of Fig.4 detached on account of the limitation of the sheet.

art of the machine shown in Fig. 4 inverte Fig. 6 is a detail in vertical sectionof apparatus controlling the pressure of the letters against the canceling and stamping dies. Fig. 7 is'a plan view of the apparatus of Fig. 6 with a part sectioned on line 7 7 of said Fig. 6. Fig. 8 is a vertical section of the ink-holder and feeder. Fig. 9 a plan view of the inkhold er with the cove'r removed. Fig. 10 is a horizontal section of a clutch of one ofthe delivery feed-rolls, permitting overrunning of the last feed-roll at higher speed for accelerating the delivery 'and affording clearance between-the letters to avoid conflict between them. Fig. 11 is a vertical section of said clutch on line 11 11 of Fig. 10. Fig. 12 is a detail in sectional elevation of apparatus for effecting the individual separation of the letters feeding into the stamping-dies. Fig. 13 is a plan view of the apparatus-shown in section in Fig. 12. Fig. 14 is a plan view of the canceling and stamping dies and their,

- arrying-roll. Fig. 15 is a face view of the canceling andstampingapparatus of Fig. 14.

A represents a'stand of any suitable construction supporting the bottom plate a of a case, having a pendent flange b embracing the top of the stand for confining the'case in position, on which plate are upright plates 0, one at each end, supporting a table (1, said table and a plate d, endent from the table, being the su ports of the bearin s of various upri ht shafts and caring emp oyed in the Inec anism to be described. The plate a and sides 0 also support lateral brackets e, carrying the infee'ding andoutfeeding letters to be stamped'and discharged.

which the power is to be ap lied in any apmain driving-shaft h, and it carries a part'i of a coupling at its upper end for en agin by the counterpart w1th the vertica sha t k, which carries at its up er end above table the canceling-die, l'an the postmarkin die m, which are attached by the disk-hea n of said shaft k. These dies l and m are detachably connected tohead n, as usual, for readily changin and adjusting them when required.

ing a socket ofthe head 1, with a set-screw Z for clamping it fast and a dowel-pin Z The die m has a central detachable part m, with a ingpar't m also removab e and fastened with a clamp m. The disk-head n is notched in the.periphery for space ,in' which to place the clam The means of connecting and securin 1 t ese dies may, however, be varied at w1 The shaft k carries below plate da spurwheel 0, that ears with a spur-wheel on the shaft q, whicfi gears with spur-whee g on a shaft g carrying feed-roll r on its upper end,

envelops to the die-head n, withwhichpresserroll t coacts. i

Shaft (1 drives by a belt a and suitable pulleys the feed-roll o and also drives by another belt to and suitable pulleys the feed-roll m. Said shaft q drives by'the bevel-wheels 33 the spectively gear by bevel-wheels 34 for their operation, and it also drives bybevel-wheels 31 shaft 30 and bevel-wheels 29, shaft 11 carryingv roll 6. I

The letters to be stamped and canceled The stand A supports an upright shaft f, to

proved way, as by the be've -wheels 9 and a line-shaft 34 with which the feed-rolls 5 re The die has a stem Z (dotted,Fig. 14,) enter- I set-screw m for fastenin it, and a surroundwhich coacts with feed-roll s to deliver the and with one end against gage-rod 4 and gently i shoved along by the pusher 3 on to rolls 5 and up against a guard-plate y and roll ac.

Said roll pushes the one in advance along to another roll '0 against a stop 7, which temporarily arrests the forward movement of the letter, while a reversely-revolving retardingroll 6, eoacting with roll 1), holds back the rest in case any others stick to the first, so as to be carried along with it until a lateral pusher 8 is thrust forward by the crank-pin 9, carried by the disk 10 on the upper end of the shaft 11, to which roll 6 is attached for being operated, said crank-pin working in a slot 12 of the slide-plate 13, carrying usher 8, the shank of which, 14, works in a slideway 15, in which it is confined by a clamp-screw 16 set in a bridge 17 and reaching through a slot 18 of the said shank and the slot 19 of the slideway-plate 20 into the base 21. (See Figs. 12 and 13.)

It is desirable that the roll 6 be capable of yielding under excessive pressure, as when any hard substance contained in a letter happens to enter between rolls 0) and 6, and it is also desirable that roll 6 may be adjusted.

slightly relatively to roll 2) for assorted letters of different thickness. The clamp-screw 16 is therefore not too tightly set in, so that the shank of slide-plate 13 and the slide-plate 20 may shift back, and shaft 11 is mounted in a bearing 22 just below roll 6, that is carried on one end of a sliding rod 23, having bearings 24in the supporting-base and provided with a coiled spring-25 to maintain normal pressure of roll 6 a ainst roll 12.

On the outer en of rod 23 an arm 26 is rigidly attached, extending upward along the side of the supporting-base and has a studpin 27 sliding in and out of a hole in the supporting-base to steady the arm, and said arm also carries a temper-screw 28 to adjust roll 6 relatively toroll "v for the letters of varyin thickness. The shaft 11 has a universa joint at 28 to allow roll 6 to be thus adjusted. This feed apparatus is, however, not claimed herein, being the subject of a divisional application, filed January 19, 1905, Serial No. 241,726.

The pressure-roll s cpaeting with roll 1' is mounted on forked arms 35, pivoted at 36 for yielding to excessive pressure, and a spring 37 is provided to press said roll against roll-r. Roll t (see Figs. 6 and 7) is carried in a fork 38, having two shank-rods 39 and 40, slidably supported in the base 41, with a coiledspring 42 on rod 39 to press it up into bearing contact with the die-roll n. The other rod controls the fork against rotation in the bearings by the arm 51 working in the slot 52 of the base. The roll t has to be opened relatively to the die-roll for'admitting 6 5 the letters between them freely, for which shaft 7c carries a cam 48 below the cable (I, which at the proper time takes effect on a shoe 49, carried on the end of a slidable rod 50, which has an arm 50 taking effect on arm 51 of rod 40 and opening roll t as soon as the letters are engaged by the succeeding rolls 53 and 54. When so opened, an elbowlever 44, pivoted at 45 and ranging at one end over the feedway of the envelops just above the die-roll and roll t and at the other end carrying a stop-finger 44 is made by a spring 45 to swing said finger in front of the stop-lug 46 on rod 40 and hold said roll t open until the next envelop enters between roll t.

and the die-roll to be treated? The tri ping of the stop 46 at this time to allow r0 1 t to grip the letter is caused by the-letter entering between part 44 of lever 44 and the guardplate 44, along which the letters pass and having a slot 45 in which said part 44 of the lever rests while holding-roll t is open and crowding said lever back, so as to release finger 44 from stop 46 when roll 25 closes and the parts assume the positions represented in Fig. 7. Immediately following the dieroll a and the pressure-roll t the envelops enter between rolls 52 and 53. The roll 52 is carried on the upright shaft 54, which is driven from the shaft 55 by pulleys 56 and 56 and belt 56. Wheel 0 drives shaft 55 by pinion 57, and the roll 53 is mounted in the forked arms 57, pivoted at 58 and having a spring 59 to maintain the pressure against roll 52. The shaft 55 carries delivery-roll 60, with which a presser-roll 61 coacts, which is mounted in the forked arms 62, pivoted at 63 and having a spring 64 to press roll 61 onto roll for the proper bite on the envclops. From rolls 60 and 61 the envelops pass along the guard-plate 64, set up edgewise at the head of the descending-chute rods 65 until stopped by the gage-rod 66 in front of a triangular-shaped rotating pusher 67, the points of which crowd the letters one after another against the retarder 68, which slides down the chute with sufficiently retarding friction to maintain the upright cdgewisc condition of the envelops. This retarder is shifted up to close proximity to the pusher at the beginning of the operation, the previously stamped and canceled batch having been removed. The usher-shaft 69 is driven from shaft 55 by a belt 7 0 and suitable pulleys. The stop-gage 66 is adjustable along ways 71, in which it is supported to adapt it for letters of different lengths which are assorted properly for different adjustments of the gage to begin with.

It is desirable that the feed movement of the letters be accelerated after they escape from the die-roll for better clearance. of each other in entering upon the disel1arge-way. Therefore the delivery feed-roll 60 is made larger for greater surface speed and roll 52 is provided with driving mechanism allowing it while the letters are subject to the acceler=- ated speed of roll 60, and which engage the ratchet-teeth 56 and drive at the normal rate of speed due to pulleys 56 56 and the belt 56 when the overrunning ceases.

For the a plication of the ink to the dies 1 and m an in fountain 71 is able proximity to the die-rol and dctachably secured in any approved Way, as bya clamp, (indicated at 72,) for ready application and removal, with adistributing-roll 73 intermediate of them to receive the ink from the wick77 and deliver it to the dies. It is mounted on a shifting support 74, pivoted at 75 and having a lever-arm 76, by which to .swing it against the feeding-wick 77 of the fountain from time to time to replenish the charge of ink and to swing away from the dierollentirelv when the ink-fountain is reward into the b0 moved for cleaning the dies-from time to time. A kee er-latch 78, pivoted at 79 and having a note 80 to engage the end of the lever-arm, is provided to 0 d the distributing-roll in. the working position. A spring 81 (dotted, Fig. 1) keeps said latch in engagement with said lever-arm, and a finger-piece 82 on the free end facilitates the applicat on of the fingers for manipulating the latch.

The ink-fountain contains a centrally-located wick-holder 83 directly underv the ccver84, in which a wick 85, referably of round form, is suspended with t e upper end turned over the top .of apartition 86, separating a passage-way 86 from the main bod of the fountain to a lateral slot 87, throug the side in which the before-mentioned wick 77 is, laced for contact with the roll 73. Where the wick turns over the top of the .partition 86, a clamp-disk 88'is fixed with an adjusting-screw 89 in the center boss 90 of the cover to regulate the feed of'the ink by clamping the wick more or less tightly. The vertical guard-flan es 91, upwardlfy projecting on each side a ove the top 0 passagewa 86, are intended to prevent overflow of ink from the up er end of the wick backd y of the fountain. inking apparatus is, however, not claimed herein, being the' subject of a divisional application, filed January 19,1905, Serial No. 241,727.
